C. Garciaviguera et al., DETERMINATION OF AUTHENTICITY OF FRUIT JAMS BY HPLC ANALYSIS OF ANTHOCYANINS, Journal of the Science of Food and Agriculture, 73(2), 1997, pp. 207-213
A HPLC technique for the analysis of anthocyanins from various fruit j
ams is described and used to monitor the stability of anthocyanins dur
ing processing. Commercial jams made from strawberry, blackberry, rasp
berry, blueberry, blackcurrant and cherry were studied. Each product h
ad a distinctive anthocyanin pattern which enabled identification and
characterisation of each jam. The manufacturing process had no effect
on the qualitative anthocyanin profile.
